I think realistically this is needed for the Y2038 work as well if we
want to support building glibc with older kernel headers.  “glibc 2.31
will have Y2038 support and rseq support, but only if it runs on a
current and it happens to have been built against sufficiently recent
kernel headers” is a bit difficult to explain.  The current kernel part
is easy enough to understand, but the impact of the kernel headers on
the feature set has always been tough to explain.  Especially if you
factor in vendor kernels with system call backports.

Thanks,
Florian
